Some Internet Measuremen t Thoughts � Richard Barnes � BBN Technologies � RIPE MAT Co - Chair �

RIPE MAT WG � • RIPE is the RIR for Europe; RIPE NCC is their secretariat � • RIPE has working groups on particular topics � • MAT == Measurement, Analysis, and Tools �

About MAT � • Network measurement issues of interest to the operational community � – Intersection of operations and research � • Community input for NCC - operated measurement systems � – TTM, RIS, ATLAS, … �

Example topics � • High - speed tra ffi c classification techniques � • Visualization of geolocation - based measurements � • RIPE ATLAS system architecture � • <your topic here> �

Something we’ve been discussing � • As discussed at AIMS 2010, there are persistent data - sharing problems in the research community � – Collect > analyze > publish > delete � • Harder to get data to work with � • Limited comparability of results � • Limited coverage of the Internet � – Limited generalizability �

Can we make this better? � • Overcome some barriers… � – Incentive: Why will people participate? � – Technical: How to move data? � – T rust: Neutral platform; how to manage privacy? � • … and maybe make some improvements � – More numerous and more diverse sources � – Better characterization of data sources � – Easier access to data sources �

What about a meeting point? � Ac#ve, ¡ Ac#ve, ¡ Academic ¡ Passive ¡ Passive, ¡… ¡ Opera#onal ¡ Academic, ¡ Academic, ¡ Opera#onal ¡ Opera#onal, ¡… ¡ Source ¡Brokering ¡ Commercial? ¡ Data ¡Formats ¡ Usage ¡Terms ¡

Where we are now � • Initial “RIPE Data Repository” � – http://labs.ripe.net/datarepository � – Basically an FTP server with some data sets � • 7 sources: RIPE NCC, U. W ashington, W aikato, et al. � – Sign up with RIPE labs to get access � • Initial discussions in the MAT WG � – General interest across the community � • Initial discussions with some data providers �

Questions � • Is this an interesting idea? � • W ould you contribute data? � – How should data get in? FTP? Real - time? � • What would you want to get out of this? � – Academic, commercial data sets? � – Active, passive measurements? � • What sort of tools would be useful here? �

One more thing… �

BBN NetTest � • E ff ort to make a more useful, more open network measurement tool � – More interesting tests ( HTTP proxy detection )� – More open data access ( your own; groups )� • Currently very early in development � – Ideas for where to take this? � • Main clients: Java W eb Start, J2ME � – http://main.nettest.bbn.com/ � • V ery preliminary Android client � – https://main.nettest.bbn.com/android.html �
